Step 1: Changing the Code
The first thing you need to do is to go to the blog you want to ping and then add it to your bookmarks or favorites.

Once it is in your favorites or bookmarks, open the list and right click on the blog name. For instance, in the example here, I saved Commodities Investing in my bookmarks. Then I right click on Commodities Investing in the list.
This will bring up a list of different actions. At the bottom of the list is “properties.” Left click on properties and you will see the following screen:

Now, if you were to “ping” with the properties as they are, the blogging/pinging would not be effective. This is one of the “secret” steps that took a long time to figure out. For the blogging and pinging to work effectively, you are going to have to change the location field.
Currently, the location field has your URL. You need to add a string of text BEFORE this URL. Here is the string of text that you need to add:
http://api.my.yahoo.com/rss/ping?u=

So in the case of the example above, the old location was htt://www.commodity-investing.info/.
The new location is:
htt://api.my.yahoo.com/rss/ping?u=htt://www.commodity-investing.info.
Let’s take another example because this is VERY important to get correct. If your location URL is currently:
name-of-blog.blogspot.com, the new location will be htt://api.my.yahoo.com/rss/ping?u=htt://name-of-blog.blogspot.com.
